Sizemodo: New MacBook and MacBook Pro vs. Their Forebearers
The new MacBook and MacBook Pro may be molded by hand from a single piece of adamantium or whatever, but how do they size up to their previous versions? The new MacBook Pro actually has a larger footprint (X Y) than the old MacBook Pro, but it's also slightly thinner (tough to tell in person). But the new MacBook, on the other hand, has a nearly identical footprint (X Y), but seems much thinner than the old MacBook. And the numbers agree.

In other words, to the naked eye, big improvement on the MacBook dimensions. Minor improvement Maybe a wash or even a step back on the MacBook Pro dimensions. 0.13 inches doesn't sound like much, but combined with beveling, it makes the new MacBook look and feel much more like premium device.
